Now that the cold weather is here the heater on our 6690 is not working it is a electric heater run off a separate alternator,  the the heat works intermittently  perhaps a lose connection just wondering if anyone hear has experience with this problem

Ours works great (knock on wood)!!! If it works intermittently maybe it could be a loose connection. I've got a shop manual that shows the wiring diagrams.

The electric heater has always been a problem on those tractors. Heater core goes bad, circet board goes bad, + they are a bi--- to work on.   MACK
